What is time? #cosymorg #science #time
When a black hole evaporates, is the information about what fell in preserved or destroyed? #cosymorg #science #information_paradox
The information describing a volume of space may be entirely contained on its boundary surface. This article examines where that idea came from, what the AdS/CFT correspondence established, and what it implies about the nature of space and information. #cosymorg #science #holographic_principle
A technical overview of spacetime singularities from the Penrose-Hawking theorems to the limits of stellar collapse. Examine how LQG, string theory, and asymptotic safety resolve the infinite curvature of the classical manifold. #cosymorg #science #singularities
Is spacetime smooth and continuous, or does it have a fundamental granular structure? This article examines the theoretical and experimental evidence for spacetime discreteness. #cosymorg #science
What if the failure of quantum gravity was never a problem with the theory but only with the method? What if gravity, at the highest energies, simply stops changing? #cosymorg #science #asymptoticsafety
String theory replaces point particles with one-dimensional strings, providing a description for gravity. This article examines the theory's development, its concrete results, and the landscape problem it has not resolved. #cosymorg #science #stringtheory
Loop quantum gravity suggests spacetime is not continuous but quantised, leading to new insights into black holes and the early universe. In the article, explore how far this idea goes and where it falls short. #cosymorg #science #LQG #BigBounce #SpinFoam #SpinNetworks
